Question

In the figure below, two 9.80 kg blocksare connected by a massless
string over a pulley of radius1.15 cm and rotational
inertia3.40 10-4 kg
m2.The string does not slip on the pulley; it is not
known whetherthere is friction between the table and the sliding
block; thepulley's axis is frictionless. When this system is
released fromrest, the pulley turns through 1.40 rad in79.0 ms, and
the acceleration of theblocks is constant.
